Allow ability to specify jar baseName for gradle projects

The Gradle project initializr does not provide the ability to specify the JAR name, so application builds generate a JAR with a default name (i.e. app-x-x-x.jar). Obviously, after generating the project, developers can tweak the build.gradle using this code:

jar { baseName = 'my-app-name' }

This directs Gradle to generate a JAR “my-app-name” prepended to the file name. However, it would save a little time if the initializr had an optional form field that allowed you to set the JAR base name. The initializr could then generate this configuration section for you in the build.gradle.
